This document is intended for Server Administrators with sufficient technical skills. 

XTRF Platform application is expected to be run as a backend service in DMZ, not directly exposed to the Internet. Therefore, we do not support installing SSL certificated directly into XTRF.

In order to expose the proper HTTPS endpoint, you should use a tool called TLS termination proxy, or load balancer. This tool intercepts HTTPS requests, allowing you to enforce access rules, log traffic and perform other actions typical to middleware. XTRF backend socket listens on HTTPS on port 8443.

One example of such tool is Apache HTTPD, which is free and widely available for all operating systems.

Apache HTTPD SSL configuration

Below you can find information necessary for setting up an SSL certificate for your XTRF Platform installation with an Apache server to serve as a proxy for XTRF Platform. The SSL certificate can also be installed by our specialists for an additional fee. Please contact the XTRF Support Team for details. Please bear in mind to always use the latest Apache and OpenSSL releases for maximum security and update them regularly.


  • The Apache is required to be installed on the server. Ports 80 and 443 cannot be used by any other application.
  • The CSR can be generated from Apache. For help, refer to these instructions from your chosen SSL provider, or at https://www.digicert.com/kb/csr-ssl-installation/apache-openssl.htm
  • The certificate file is put on the server. The path to the file is indicated in a configuration file, which you can find in Apache's Configuration module. In the same configuration file, you should point to the domain name and ports. XTRF Platform backend runs on port 8443.



SSL Settings

You might also fine-tune the SSL settings according to the current best recommendations. For example, you can find helpful solutions under the following link:




Apache Settings for HTTPS Proxy (Windows OS)

You should download the Apache HTTPD distribution from https://www.apachehaus.com/cgi-bin/download.plx

Please notice that this configuration requires at least Apache 2.4.12. Add the following code snippet to your Apache config and enable modules: rewrite, logio, proxy, proxy_sslproxy_ajp, proxy_http, headers, status and ssl (if proxy_ssl isn't available) for Apache.

Also please find in the httpd.conf  below line:

And check if it is  uncommented (if there is "#" at the beginning of the line, you have to remove it). In latest versions of Apache (>2.4.17) you should consider enabling HTTP/2: https://httpd.apache.org/docs/2.4/howto/http2.html

As of early 2018, the default Apache HTTPD distribution enables the following file:

You should disable it as it will conflict with the SSL installation - simply prepend it with #.

You can use the following file as a base for your configuration: xtrf-ssl-windows.conf

Apache Settings for HTTPS Proxy (Debian/Ubuntu)

Please notice that this configuration requires at least Apache 2.4.7. This requires at least Debian 8 Jessie or Ubuntu 14.04 Trusty. Execute the following commands to enable required modules:

In latest versions of Apache (>2.4.17) you should consider enabling HTTP/2: https://httpd.apache.org/docs/2.4/howto/http2.html

Please create a file /etc/apache2/sites-enabled/xtrf.conf with the following content (adapt the hostname and SSL certificate location): xtrf-ssl-linux.conf
